Hello, I just wanted to show a few pictures of my 45", OHV conversion I finished awhile ago. I went a different route than the standard Magnum conversion, opting for an exposed valvetrain. My favorite model is the Harley DAH. Since I will probably never own one, I figured I'd mix some ideas I had together, spend three years on it and, here ya go!!

Thanks for the compliments! It runs great and has a huge amount of torque! I have to keep reminding myself to take it easy on the poor little transmission. I'm sure it would not take much to peel it open. I did use one of the new european reproduction transmission cases, hoping for better quality aluminum from todays metalurgy, but was disappointed in the machining. I think all I gained was less money in my pocket!!!

I love how you referred to the "standard magnum conversion"! If a 45 Magnum is standard, your motor is pure exotica. Drool worthy. I would be interested in some elaboration on the 4spd euro tranny. I was considering one until your comment. Could you make a critique of it with your observations/concerns with the unit?

Scaryguy- My transmission is still a three speed. I only bought the case. I found two minor and one major problems as I built the transmission. The lid screws were 12-24 instead of the 10-24 they were originally (no big deal). There was one of the lid screws that was incorrectly located. I welded it up and re-drilled/tapped it (OK, mistakes happen). The last one was the distance between the shift cam shaft and the shift arm gear. They were .050" too close together!!!! And to top it all off, installing the shift gear is one of the last steps, so it all had to come apart again to fix it. I did not buy the four speed for several reasons. One, too expensive. Two, untested. Three, The HP the bike puts out will most likely ruin the trans at some point, I figured I would ruin the cheaper, easier to get parts. I do not believe fourth gear was any higher a ratio then third was in the three speed. Its only benefit was smaller "steps" between gears. That would benefit the stock 45", but with close to four times the HP in my engine, I don't need it.

Wow, It's beautiful. I also have loved the DAH since I first saw one in person. I bought a WR motor from an old racer back in the early 70's. The motor was in his basement in Springfield, MA where he also had a DAH. He would not sell it. He did let me sit on it, which was awesome. When I lived in NM there was a guy who had a couple in his collection just North of Santa Fe. Prettiest HD ever.

I found a donor (stock) neck, and replaced both it, the backbone and the tube above the engine. In the photo you can see ho much material has to be removed under the seat post casting. I also drilled out the neck and added the rear stabilizer bars, like the WR frames.
